Abstract
The performance of a method of estimating the worm burdens in young sheep flocks, by applying egg count data to a simple “formula” was evaluated on four farms in the Manawatu. On all farms there was a good fit between the estimated flock worm burden using this method and those obtained from worm counts. It is suggested that this procedure is likely to be successful in providing a reasonable approximation of the flock worm profile when 10 to 15 egg counts on randomly selected members are performed.
